  • Example: 60-year-old retiree uses 50-60% stocks vs. typical 40-50%
  1. For Pension Recipients:
  • Count pension as bond-like income
  • May allocate 10-15% more to equities
  1. Health Considerations:
  • Longer life expectancy = higher equity allocation
  • Shorter expectancy = more bonds/cash

Implementation Guide

  1. Rebalancing Rules:
  • Annual rebalancing when allocations drift ±5%
  • After major market moves (>20% change)
